Starbucks, McDonald's, and Monster Will Get Chewed Out

Wrigley moved on Wednesday to halt production of Alert, the company's chewing gum spiked with 40 milligrams of caffeine.

With the Food and Drug Administration investigating the safety of caffeine consumption -- especially in children and young teens -- the last thing that a candy company wants to be seen is as harmful to children.

Naturally, this leads one to wonder how Starbucks and McDonald's -- two retail giants that have moved from traditional coffee to offer icy coffee beverages that have been sweetened -- as potential targets in the attack on caffeine.

In this video, longtime Fool contributor Rick Munarriz explains why he believes that Wrigley's decision to stop producing Alert will have negative ramifications for companies making beverages that pack far more caffeine per serving.
